Walmart is selling a CyberPowerPC prebuilt gaming desktop for $1,549, down from $2,139. The system includes an Intel Core i7-14700KF processor, 32GB of 6000MHz DDR5 memory, an Nvidia RTX 5070 Founders Edition GPU with 12GB VRAM, a 1TB PCIe 4.0 SSD, and CyberPowerPC's MA-O1 case with RGB controls. It ships with a keyboard, mouse, and a one-year parts and labor warranty.
A developer has built a web-based emulator that recreates the IBM 1620 Model 2, a 1960s transistorized decimal computer originally aimed at scientific and engineering users. The project also includes IPL-V, the 1963 operating environment originally used on the machine, letting users run period software directly in a browser.
Researchers Hao Zhang and Mathieu Dumberry report in Nature that gravitational coupling between Earth's solid inner core and its mantle explains multidecadal changes in day length of a few milliseconds. They combined seismological data on inner-core rotation with a model of outer-core flow derived from magnetic field measurements to reach this conclusion.
A study published in Nature reports that small variations in the length of Earth's day, on the order of milliseconds over decades, can be explained by competing gravitational, mechanical and electromagnetic forces between Earth's solid inner core, molten outer core and rocky mantle. Researchers, including geophysicist Mathieu Dumberry, had long suspected core-mantle interactions caused these fluctuations but lacked clarity on which specific forces were responsible.
Researchers analyzed length-of-day (LOD) records from 1964 to 2019, after removing known effects from the atmosphere, oceans, tides and surface mass changes, to isolate multidecadal variations. They modeled these residual variations using torque equations that account for gravitational pull from the inner core alongside electromagnetic and topographic coupling at the core-mantle boundary, finding that gravitational torque from the inner core contributes to the slow, multidecadal changes in how long a day lasts.
Microsoft has expanded Automatic Super Resolution, its NPU-driven upscaling feature built into Windows, to Copilot+ PCs powered by Intel's Core Ultra Series 3 chips, a capability previously exclusive to Qualcomm Snapdragon X devices. The feature aims to boost frame rates in games rendered at up to 1080p, with Microsoft citing gains of up to 15% in titles like Assassin's Creed Valhalla, targeting a 60 FPS threshold.
Newegg is selling the ABS Cyclone Aqua gaming desktop for $1,199.99 after applying the code SSF73826, down from a list price of $1,699.99. The build pairs an Intel Core i7-14700F with 32GB of DDR4 RAM, a 1TB PCIe 4.0 SSD, and a Zotac RTX 5060 Solo GPU with 8GB of VRAM, aimed at 1080p gaming.
An Android Authority writer detailed how his family, after briefly trying an iPad, ended up adopting Walmart's Onn tablet lineup, including the Onn Core 7-inch and Onn 11 Pro models. He found the devices, priced between roughly $97 and $388, offer aluminum builds and solid performance rarely seen in that budget range from other unbranded competitors.
Google opened preorders Monday for its new 'Googlebook' laptops starting at $899, offering a choice of Intel Core Ultra Series 3 or Snapdragon X Elite chips paired with NPUs for AI processing. The devices ship October 4 in the US and a day later in Canada, the UK, Ireland, France, Germany and Australia, featuring deep integration of Google's Gemini assistant into the operating experience itself.
Google's hardware partners have launched their first Googlebooks, all available for pre-order, featuring premium specs including at least 16GB of RAM and batteries rated for 14-16 hours of use. Acer, ASUS and Lenovo models use Intel's Core Ultra 5 Series 3 chips, while Dell and HP opted for Qualcomm's Snapdragon X Elite processor. Each device includes a signature 'Glowbar' light array on the lid that displays battery status and animations during Gemini interactions.
A technical essay revisits Gary Bernhardt's decade-old 'Functional Core, Imperative Shell' architecture, arguing that the key property enabling easy testing isn't functional purity itself but determinism. The author suggests that state machines and other deterministic constructs can achieve the same testability benefits as pure functions, broadening how developers might structure isolated, predictable 'core' logic versus the messier, IO-heavy 'shell' that talks to the outside world.
Prusa Research and Bondtech have released the INDX, a toolchanging system that can print up to eight colors or materials using slim, moving-part-free toolheads mounted on Prusa's CORE One platform. The system ships pre-installed on new CORE One+ Gen 2 printers or as a $749 conversion kit for existing CORE One owners, and Bondtech also sells it separately as a DIY kit for other open-source printers.
